Derek Velzy replied to Mitchell Drake's discussion Multiple Origins Of Life? in the group SES 311:Essentials of Astrobiology
"Cool to see that you drew similarities in the development of modern man to the development of the origin of life. I also considered this to be an option after one of the readings mentioned something about "convergent" evolution (I believe…"

The Most Adaptable Species

When we think of the most adaptable species, what comes to mind? Camels are able to survive without food or water for months, cockroaches are said to have survived the atomic bombs on Hiroshima and Nagasaki in World War II, and Emperor Penguins are able to make journeys 60+ miles long with their last meal being four months earlier.

Why Limit Our Definitions?

Astrobiologists, amongst other biological scientists, have not yet settled on a standard definition for what they consider to be life; this is because there are so many loopholes and exceptions to each new definition-theory that we come up with. To a FAR lesser degree it is almost like trying to come up with a standard definition of a hamburger. Is it two separate bread buns with a beef patty in the center? What about protein style at In-N-Out where the buns are replaced by a lettuce wrap?…See More
